pollution from agricultural crop fields and urbanized regions oftentimes have elevated concentrations of dissolved organic nitrogen (DON) in stormwater runoff, which are difficult for microbial communities to decompose. The impact of elevated DON can be circumvented through the use of green sorption media, such as Biosorption Activated Media (BAM) and Iron-Filing Green Environmental Media (IFGEM), which, as integral parts of microbial ecology, can contribute to the decomposition of DON. To compare the fate, transport, and transformation of DON in green sorption media relative to natural soil (control), a series of fixed-bed columns, which contain natural soil, BAM, and two types of IFGEM, respectively, were constructed to compare nutrient removal efficiency under three distinct stormwater influent conditions containing nitrogen and phosphorus. Citations are important for a journal to get impact factor. Impact
factor is a measure reflecting the average number of citations to recent
articles published in the journal. The impact of the journal is influenced by impact factor, the
journals with high impact
factor are considered more important than those with lower ones. To increase the visibility and ease of use of
open access scientific and scholarly
journals OMICS Group top online publishing
journals are
indexed in different indexing and archiving services.
